Module Federation#

Module Federation allows JavaScript applications to dynamically load code from other builds at runtime. This feature has several use cases, including:

• Independent applications (known as "microfrontends" in microfrontend architecture) to share modules without the need to recompile the entire application.
• Distributed teams to work on different parts of the same application without the need to recompile the entire application.
• Dynamic code loading and sharing between applications during runtime

Rspack supports two versions of Module Federation: Module Federation 1.0 and Module Federation 1.5.

• Module Federation 1.0 is the current implementation of ModuleFederationPlugin in Webpack.
• Module Federation 1.5, among other things, adds runtime plugin functionality to 1.0, allowing for the extension of Module Federation's behavior, functionality, and providing control inversion to users.
